U dhoofinta PVC ee Shiinaha ee Hindiya
Shiinahadhoofinta PVCHindiya,
Sannadkii 2021, dhoofinta PVC ee Shiinaha waxay gaartay heer taariikhi ah oo ah 1.7538 milyan tan, taasoo aad uga sareysa 1.0889 milyan tan ee 2016. Ilaa rubuci afaraad ee 2020, adduunka ugu weyndhoofiyaha PVC, Maraykanka, ayaa la kulmay xoog majeure si loo yareeyo wax soo saarka, iyo dunida ugu weynsoo saaraha PVC, Shiinaha, oo keenay xilliga dhoofinta ugu wanaagsan.Marka lagu daro mowjadda qabow ee Bandhiga Gu'ga ee 2021, farqiga Dhoofinta ee Maraykanku wuxuu socday rubuci afraad ee 2020 ilaa rubuci saddexaad ee 2021.
Sida soo dejinta ugu weyn adduunka - Hindiya, sannadeedkeedasoo dejinta PVCwaxay u baahan tahay in ka badan 1.5 milyan oo tan, sannadihii la soo dhaafay, horumarka degdega ah ee dhaqaalaha Hindiya, baahida soo dejinta ayaa sii kordheysa.Iyada oo ay saamaysay awoodda majeure ee Maraykanka iyo dhimista dhoofinta, Fursadda Shiinaha ee dhoofintaPVC ee HindiyafurtoLaga bilaabo Maarso ilaa Abriil 2021, macaamiisha Hindiya waxay ka walaacsan yihiin yaraanta sahayda caalamiga ah iyo qiimaha kor u kaca, sidaas darteed tiro badan oo alaabada PVC ah ayaa la keenaa, sida laga arki karo shaxanka soo socda.Si kastaba ha ahaatee, sanadka 2022, qiimaha badeecadaha Shiinaha ayaa ku jira ugu hooseeya qiimaha caalamiga ah, iyo canshuurta ka hortagga qashinka ee PVC ee Shiinaha ayaa dhacaya Febraayo.Iyada oo faa'iidada qiimaha, PVC Shiinaha si degdeg ah u qabsadeen suuqa Hindiya.
Waxaa jira baaxad weyn oo iskaashi ah oo ka dhexeeya Shiinaha oo ah dalka ugu wax soo saarka badan adduunka iyo Hindiya oo ah dalka ugu badan ee wax soo dhoofsada;Marka laga reebo ganacsigii hore ee kahortaga qashinka, dhoofinta PVC ee Shiinaha waxay ka leexatay faa'iidada farqiga sahayda caalamiga ah waxayna isu rogtay faa'iidooyinka qiimaha caalamiga ah.Dhinaca kale, suuqa gudaha ee Shiinaha ayaa si degdeg ah ugu baahan dhoofinta si loo yareeyo cadaadiska saadka gudaha muddada gaaban.Dhanka kale, shirkadaha qaarkood waxay u jeestaan iibka PVC ee dibedda si ay u horumariyaan nidaamkooda ganacsi.

PVC waa erey la soo gaabiyay oo loogu talagalay chloride polyvinyl.Xabagta waa shay inta badan loo isticmaalo soo saarista caagagga iyo caagadaha.Xabagta PVC waa budo cad oo caadi ahaan loo isticmaalo in lagu soo saaro heerkulbeegyada.Waa walxo synthetic ah oo si weyn looga isticmaalo adduunka maanta.Polyvinyl chloride resin waxa uu leeyahay sifooyin aad u wanaagsan sida alaab cayriin oo badan, tignoolajiyada wax soo saarka ee bislaaday, qiimo jaban, iyo adeegsiyeedyo kala duwan.Way fududahay in la farsameeyo waxaana lagu farsamayn karaa qaabaynta, laminating, qaabaynta duritaanka, extrusion, calending, dharbaaxada qaabaynta iyo habab kale.Iyada oo leh astaamo jireed iyo kiimiko oo wanaagsan, waxaa si weyn loogu isticmaalaa warshadaha, dhismaha, beeraha, nolol maalmeedka, baakadaha, korontada, adeegyada dadweynaha, iyo beeraha kale.Xabagta PVC waxay guud ahaan leeyihiin iska caabin kiimiko oo sarreeya.Aad bay u xoog badan tahay oo u adkaysataa biyaha iyo naaxinta.Polyvinyl chloride resin (PVC) waxaa lagu farsamayn karaa baco kala duwan.PVC waa balaastiig khafiif ah, raqiis ah, oo deegaanka u wanaagsan.Pvc Resin waxaa loo isticmaali karaa tuubooyinka, daaqadaha daaqadaha, tuubooyinka, maqaarrada, fiilooyinka fiilooyinka, kabaha iyo ujeeddooyinka kale ee guud ee alaabta jilicsan, profiles, dhejisyada, muraayadaha, duritaanka, naqshadeynta, kabaha, tuubada adag iyo alaabta qurxinta, dhalooyinka, xaashida, jadwalka duritaan adag iyo qaabaynta iwm iyo qaybo kale.
Astaamaha
PVC waa mid ka mid ah resins thermoplastic ee ugu isticmaalka badan.Waxaa loo isticmaali karaa in lagu sameeyo alaab adag oo adag, sida tuubooyinka iyo qalabka wax lagu dhejiyo, albaabada muuqaalkooda leh, daaqadaha iyo baakadaha.Waxa kale oo ay samayn kartaa alaabo jilicsan, sida filimaan, go'yaal, fiilooyinka korantada iyo fiilooyinka, sagxadaha sagxadaha iyo maqaarka synthetic, iyada oo lagu daro caagadaha.
